Hello again!

I was wondering if you could help me. In RCVD, chapter 16, it does 2 examples, a full one and a simplified one. To calculate roll rates, it uses the following formula:

Roll rate= WH / (desired total roll gradient)

However, in the first example, W is the full weight of the car, but in the second one, it's only the sprung weight. Also, in this paper from OptimumG it uses the full weight too http://www.optimumg.com/docs/Springs...Tech_Tip_2.pdf

You get quite different results using both definitions, so I was wondering if you could help me. It seems to me that it's more logical to use the sprung weight for this calculation, since the springs and antiroll bars control the sprung weight, but I could use some guidance.
